BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates to retaining devices and, more specifically, retaining devices for securing medical wires, catheters, guidewires, electrical lines, cables, tubing and other elongated members during medical procedures.

Discussion of the Related Art

Guidewires and catheters are used in a variety of different medical procedures, for example, during angiographic, endovascular, or surgical procedures. Guidewires are typically used to position catheters in a body lumen, for example arteries, veins or natural orifices within a mammal. The leading end portion of the guidewire is typically introduced into the body through an incision or natural orifice and then advanced to the treatment area. A catheter can be threaded over the guidewire, and advanced over the guidewire to the treatment area. A single guidewire can be used to deliver multiple catheters to the treatment area within the body lumen. This is normally accomplished by withdrawing and removing the first catheter from the wire while leaving the leading edge of the wire in place within the body lumen, and then threading a second catheter over the wire and advancing down to the treatment site. Multiple guidewires and catheters can be inserted into the body lumen at the same time.

When the guidewire or a guidewire and catheter combination is placed within the body lumen, a loose trailing end portion extends out of the patient from the entry point. This trailing end portion can be difficult to manage and requires special attention from the medical staff to ensure it does not become contaminated, tangled or confused with other wires in the procedural area.

Therefore, a device and method for retaining the trailing end of guidewires and catheters is desired.

Reference will now be made in detail to an embodiment of the present invention, example of which is illustrated in the accompanying drawings.

FIG. 1 illustrates a retaining device according to an embodiment of the invention. Referring to FIG. 1, the retaining device 10 is configured to hold medical lines.

As shown in the drawings, medical line retaining device 10 generally includes a flexible body with top and bottom surfaces containing at least one nonlinear slot 11 formed in the top surface. The device may include an attachment mechanism 12 coupled to the body for attaching the retaining device to a substrate. As shown in FIGS. 1 and 2, the retaining device 10 includes a wedge shaped flexible body with 2 sinusoidal shaped slots 11 in the top surface and extending toward the bottom surface. The flexible body is composed of a flexible and compressible material such as a polymer elastomer or polymer foam. These materials flex to allow entry into the slot or slit where the medical line is larger than the slot width. They also allow for greater retention of the line as the material compresses around the line, particularly around the curves in the slot, and thus produce more holding friction due to the increased surface contact.

The slots 11 are dimensioned smaller than the medical line 14 and in a preferred embodiment have a v-shaped opening where they meet the top surface to facilitate entry of the medical line 14 in the slot. In this embodiment the perimeter surface of the body is ellipticalshaped and substantially perpendicular to the bottom surface. The perimeter surface may be any geometric configuration. The attachment mechanism 12 is a pressure sensitive adhesive attached to the bottom surface with a protective liner 13 over the adhesive. Other attachment mechanisms may be used. For example, retaining device 10 could be attached to a heavy, draping pad such as a mouse pad. Mouse pads are typically made with flexible, heavy polymers such as rubber, neoprene rubber, silicone, and silicone foam. A mouse pad holds to a surface without sliding due to weight, a large contacting surface area, a textured contacting surface area, and high coefficient of friction of the before mentioned materials. Alternatively, retaining device 10 could be a unitary structure with sufficient weight and surface area to hold it to the surface without sliding.

In use, a protective liner 13 is removed from pressure sensitive adhesive 12 and retaining device 10 is attached to a supportive substrate, such as a surgical drape, surgical table, bed sheet or the like, via the adhesive material. Medical line 14 is pressed into slot 11 by inserting it into the upper most section of the slot 11 first and then guiding and pulling slightly into the remainder of the slot. During insertion, the flexible material surrounding the slots moves or is deformed to accept the medical line 14, and then forms around the medical line 14 to retain it within the device 10. Retention occurs both by mechanical and/or frictional mechanisms. Mechanical mechanism is due to the body material physically surrounding the medical line 14 and preventing it from moving out of the slot 11. Frictional forces come from at least two sources, the body material pressing into the medical line 14, and the straightening force of the medical line 14 pressing into the curves of the slot 11. To remove, the medical line 14 is simply pulled upward at a force exceeding the mechanical and frictional forces holding the line in the medical slot 11.

FIG. 3 illustrates another embodiment of the invention. Referring to FIG. 3, the retaining device 10 includes a wedge shaped body with a rectangular shaped perimeter and has two sinusoidal shaped slits 11 in the top surface and extending towards the bottom surface so that slit depth (from the top surface) is greater than the diameter of the medical device 14. The slits 11 are thin cuts made into the body and width to a distance in of about 0 inches to about 0.02 inches or greater. Two slots 15 extend from the front surface to the back surface. These slots 15 communicate with and are perpendicular with slits 11. Slot 15 height is preferably larger than the largest diameter medical line to be used and width is preferably aligned with and dimensioned the same as the maximum amplitude of the sinusoidal slots 11. Alternately, slot 15 could be a slit or a round orifice.

In use, the medical line 14 is pressed into the slits 11 and moved to the bottom of the slits, the straightening force of the line 14 will cause the line to move into slots 15, thereby providing additional retention to secure line 14 into retaining device 10.

In this embodiment, the attachment mechanism 12 is attached to the bottom surface and extends out one side of the device 10. The attachment mechanism 12 is configured to secure the retaining device 10 to a substrate, e.g., table, bed sheet, a medical drape, gown and the like. The attachment mechanism 12 includes a plate shaped structure overlapping and attached to the bottom surface by an adhesive or other suitable fixing unit, e.g., screw, rivet, and the like. In this embodiment, it is configured to extend from a perimeter of the retaining device 10 and has an integral rectangular or square tab 16 removed from the plate shaped structure extending from the perimeter.

The tab 16 has three sides and a bend on the remaining side connected to attachment mechanism 12 and angled up from the plate structure top surface. Below the bent tab 12 is a rectangular or square orifice 17 in the attachment mechanism 12 approximately the same size as the tab. The tab may have at least one protrusion for aiding securement to the substrate, e.g., a barb. Other types of attachment mechanisms may also be used.

Referring now to FIG. 4, an edge or folded edge of a sheet 18 may be placed partially over the orifice 17 and under the tab 16. To secure the retaining device 10 to the sheet 18, the tab 16 is pushed down and through the orifice 17 and slightly below the plane of the bottom portion of the attachment means 12, wedging the sheet 18 between the tab 16 and orifice 17.

FIGS. 5 and 6 illustrate a substrate 18 in the locked position as viewed from above and below. This embodiment provides a simple, secure means for securing the retaining device to a sheet, drape, or gown. To disengage the substrate 18, the tab 16 is moved back out in the other direction. Other advantages of this attachment mechanism is that it can be combined with an adhesive mechanism as shown in FIGS. 1 and 2 to provide increased utility to secure to many different supporting surfaces.

FIG. 7 illustrates another alternative embodiment of the invention. Referring to FIG. 7, the retaining device 10 includes markings 19 on the top surface next to slots 11 to help identify multiple medical lines 14. The slots could be color coded. Retaining device 10 contains j-shaped slots 20 on the front surface communicating with the sinusoidal slots 11 and they extend perpendicular toward the back surface. The end of the J slot is aligned with the top of the first curve in slot 11 such that the end of the “J” will enter slot 11 at the before mentioned point. This creates a finger shaped projection at the bottom of slot 11 where the line 14 can be manually placed to obtain maximum retention.

FIG. 8 illustrates another embodiment of the invention. Referring to FIG. 8, the retaining device 10 includes slots 11 formed in a deformable material. A plate structure 21, e.g., isosceles trapezoid shaped plate, is utilized with the retaining device 10 and adhesively mounted to the front of the retaining device 10 such that the ends extend across the slots 11. The top edge of the plate structure 21 where it crosses the slots 11 has an angled surface which allows a medical line to be easily pushed past ends of structure 11 during insertion of the line 14. The purpose of plate structure 21 is to provide increased retention of the wire 14 and removal of the line 14 is accomplished by manually pushing medical line 11 into the flexible material of the body in order move around ends of structure 21. The plate 21 may also be able to rotate to allow the medical line 11 to be more easily removed.

FIG. 9 illustrates another embodiment of the invention. Referring to FIG. 9, the retaining device 10 includes slots 11 in a nonlinear configuration. The slots 11 have a tapered cross section, e.g., the slot width is greater at the bottom than at the top.

FIG. 10 illustrates another embodiment of the invention.

Referring to FIG. 10, the retaining device 10 includes a wedge shaped body with an elliptical shaped perimeter and four sinusoidal shaped slots 11 in the top surface. Each of the four sinusoidal slots extend toward a bottom surface body. In a preferred, embodiment, this distance or slot depth from the top surface is greater than a diameter or portion of the medical device 14 to be retained and the slots 11 width are sized to be greater than a diameter or portion of a medical device 14 to be retained. In a preferred embodiment, each of the slots contain a V-shaped opening cut into the slots near the top portion of the wedge to aid in receiving a medical device 14. The V-shaped opening runs parallel to the bottom surface and are collinear with the slots. It is noted that the width and depth of each slot may be different with respect to each other.

The medical devices 14 shown in FIG. 10 include a coiled guidewire, a catheter, and a straight guidewire. The wider slots in this embodiment have the advantage of easier loading of the medical device as the material does not need to be deformed to insert the medical device. Retention is accomplished by the friction caused by the bending forces of the medical device against the sinusoidal shaped slot walls. The may also be slot in a sidewall of the shaped body.

EXAMPLES

Without intending to limit the scope of the invention, the following examples illustrate how various embodiments of invention may be made and/or used.

Example 1

In this example, a retaining device similar to FIG. 10 was designed using CAD software (SolidWorks) with the following characteristics. The device was formed as an elliptical shaped measuring 3.9 inches by 2.5 inches. The top surface was angled at 25 degrees to the bottom surface and height of 0.8 inches in the front and 1.9 inches in back. The top surface perimeter was rounded to a radius of 0.15 inches. Four sinusoidal slots, spaced 0.8 inches apart on the top surface, extended to a depth of 0.6 inches from the bottom surface. A slot width of 0.080 inches at the bottom and drafts outward at a 2 degree angle to top surface. The sinusoidal slots include S shaped slots including four connected curves having a 1.40 inch curve with 0.80 inch centerline aligned vertically. The slots lots are symmetrical across horizontal centerline and mirror images across vertical centerline. A 50 degree, horizontal chamfer is cut co-linear with the slots to a depth of 1.7 inch from a bottom surface for middle slots and 1.6 inches from a bottom surface for the edge slots.

The SolidWorks file was saved as a .STL file format and used by stereolithography software to generate information needed to produce 3D models on stereolithography machines. The file was sent to Morpheous Prototypes of Torrence, Calif. to create a mold by Stereolithography and casting the part. After forming, the mold surface was sanded and polished. A two-part RTV silicone rubber having a 25 A durometer was mixed and poured into the mold, allowed to cure for 24 hours and then removed from the mold. The resulting device weighed 0.4 lbs and had a base surface area of 7.7 in.
